OIL-CAN SUPPORT.

Application filed March 1, 1918.

To all whom it may concern:

Be it known that I, HERBERT A. SANDBERG, a citizen of the United States,residing at Gordon, in the county of Sheridan and State of Nebraska,have invented new and useful Improvements in Oil-Can Supports, of

which the following is a specification.

This invention relates to supports, and more especially to receptaclestands which are vertically adjustable; and the object of the same is toproduce an adjunct for oil or gasolene pumps whereby the can or other 7liquid receptacle may be set at various heights as is often desirable.

The invention consists in a base having standards, a shelf having blocksmovable vertically on said standards, means for rais ing one block andfor looking it at the desired height, and connections between the blocksfor causing the other block to move at the same speed as the one raised.Details are set forth in the following specification, reference beingmade to the drawing which shows a perspective view of this devicecomplete, with the can in dotted outlines.

In the drawings the numeral 1 designates a base, which is preferablycircular and hollow and raised three or four inches above the floorline, and 2- and 3 are standards rising from the rear and the front sideof said base respectively, the standard 3 being notched or provided withteeth as shown at 4. Slidable upon said standards are blocks 5 and 6,the latter provided with a handle as 7 and with a pin 8 handle forengaging between and connected with the blocks is a skeleton structureor shelf 10 of a size and shape to support a can as indicated in dottedlines at C. A cord, cable, or chain 11 is connected with the forwardblock, passes down adjacent the front standards 3, around a pulley 12 inthe base 1, transversely through the base as indicated in dotted lines,around another pulley at the rear sides movable through the of the baseas indicated at 13, rises then behind the rear standard 2, passes over athird pulley 14 at the top of the same, and is carried downward andconnected with the rear block 5.

and the front edge of the shelf to rise, and

pull on the chain 11 is communicated to the rear block 5 which causes itto rise in unison with the front block. Therefore both front and rearedges of the shelf are raised simultaneously and at equal speed, andwhatever is carried on the shelf is maintained constantly in a levelcondition. When the shelf has been raised to a suficient height, the pinis actuated to engage the proper tooth 4, and the shelf comes to restatthat point. On the other hand, when it is desired to lower the shelf,the operation is reversed. This device is in no sense a counter-balancefor the weight of the contents of the can or container. It is rather ameans for causing both the front and rear edge of the shelf to rise inequal time and at equal speed. In the illustration wherein my inventionis adapted to a structure such as described, the rear edge of the shelfis exposed and might of course be grasped by hand; but it is obviousthat conditions will occur wherein it is not always posall sides oredges of such shelf, and it must be raised and lowered from one pointonly. 7
